Asymmetric Propargylation of Ketones Using Allenylboronates Catalyzed by Chiral Biphenols. — Various acyclic ketones react under microwave-assisted and solvent-free conditions to afford propargylic alcohols. Ketoester (VI) and cyclic ke-tones (VIII) provide better results under conventional heating. — (BARNETT, D. S.; SCHAUS*, S. E.; Org. Lett. 13 (2011) 15, 4020-4023, http://dx.doi.org/10.1021/ol201535b ; Dep. Chem., Boston Univ., Boston, MA 02215, USA; Eng.) — R. Steudel
